China Coal Rotary Dryer

1.Introduction of rotary drying machine :

Rotary dryer is used for the drying of such materials as slag, clay and limestone in cement, chemistry, metallurgy and building material industry. It has the advantages of strong drying capacity, balanced operation, low energy consumption, convenient operation and high output.

2.Structure of Rotary drying machine:

Rotary Drying machine is mainly consist of rotary body, lifting board, driving device, supporting device and seal rings etc.

3.Working principle of Rotary drying machine:

Since the dryer machine is obliquely installed, the materials flow to the lower end of the machine under the gravity and the rotation of the machine, and on the other hand, the materials are repeatedly lifted by the lifting board to the higher end and then spread down constantly, so that the materials will form a even curtain inside the cylinder and conduct heat exchange with the hot air inside the cylinder. Since the materials constantly spread and the water contained in them will be dried, thus achieving the aim of drying.
